Road Signs

A yellow diamond warning sign showing a truck descending a steep slope means:

Ontario road sign — Steep hill ahead — you may need to use a lower gear
Show Answer & Explanation
Correct Answer: B. Steep hill ahead — you may need to use a lower gear

A steep-hill warning gives you time to choose a lower gear before descending. Using engine braking (lower gear) reduces reliance on friction brakes, which can overheat and fail on long descents.
